Question

How do you convert 3.2 moles of Ca to atoms of Ca?

Answer 1

`1.927xx10^24` Ca atoms.

Explanation:

1 mole of any material contains the Avogadro number of particles, that is, `6.023xx10^23` particles.

Hence, by ratio and proportion, `3.2` moles of calcium will contain `3.2 xx 6.023xx10^23` Ca particles or atoms, which is `1.927xx10^24` Ca atoms.
